A little while back (cant remember which retreat), ChNN gave the lung for dorje drollo at the end of a retreat- I did not have time to write the mantra down. I would be grateful if someone could pm me how to do the practice and mantra. Is there an action mantra too?

I read on the forum here that in the short tun you can use dorje drollo instead of guru tragohur/ simhamukha. How does dorje drollo differ from guru dragphur?

Yes, in the thread I linked Malcolm said it was "a so called don dbang, a meaning empowerment" which is still more than a lung, isn't it? I'm not sure I understand the difference, though. Anyway, there is a short Adzom Drollo sadhana on TBRC also mentioned on the thread I linked. The mantra will be in that.

Donwang is indeed an empowerment. Not in the form of elaborate initiation though, since it is not necessary in the levels of Anu and Ati Yoga. The Dorje Drolod mantra is uploaded in the "Files" section of the Webcast website.

I dont remember receiving the don wang for the practice- i didnt do the retreat in february 2012, from what i heard in one of the collective practices at the end of the webcast retreats since august 2012, it was a lung. Is it still ok to do the practice without having done the earlier retreat in feb 2012?

I have to get better at writing down what lungs ChNN gives at the end of retreats, as sometimes he can drop an unexpected lung in and sometimes the pronouniation can sound v.different to whats written down.

All practices, including mantras, which ChNN Rinpoche is transmitting, are included in the books by SSI Publications. A few of them are uploaded in the Webcast website, open or restricted sections of Files.
